The scope

What "everything included" means in a Mississauga bathroom reno

A full bathroom renovation with Prime Kitchen and Bath includes everything in the room: demolition and disposal, waterproofing, floor and wall tile, the shower or tub, a workshop-built vanity with its countertop, the toilet and fixtures, lighting and an exhaust fan, plumbing and electrical hook-up, and the final clean — quoted as one itemised number in CAD with HST shown separately.

Bathrooms are the room where "renovation" most often means "someone else does the plumbing". We do not quote that way. The quote lists every element of the room, so the comparison with another contractor is line by line rather than guesswork, and so that the number you sign is the number you pay unless you change the scope in writing.

Where kitchens and bathrooms meet

The vanity is a cabinet. It is built in the same Mississauga workshop as our kitchens, to the width of your wall and the position of your plumbing, with the same soft-close drawer hardware, and its top is templated after it is installed. That is why a Prime Kitchen and Bath bathroom does not have the filler strip and the 2-inch gap that a catalogue vanity leaves behind.

Waterproofing is the job

Tile is the finish; waterproofing is the work. Shower walls and floors get a continuous membrane system, the curb or the curbless slope is built for the drain position, and the niche and bench are waterproofed as part of the same envelope. It is the step you will never see and the one that decides whether the bathroom is still dry in ten years.

  • Demolition, disposal and dust control
  • Waterproofing membrane system for shower and wet areas
  • Floor and wall tile, including niches and benches
  • Shower or tub, glass, fixtures and trim
  • Vanity built in our workshop, with countertop and sink
  • Lighting, exhaust ventilation, outlets and switches
  • Plumbing and electrical hook-up by licensed trades, with inspections
  • Final clean and a walk-through before the last invoice
How it works

From the measure to the last bead of silicone

The sequence is the kitchen sequence applied to a wet room: consultation, in-home measure, a 3D design with a written itemised quote, the vanity build in our workshop while tile and fixtures are ordered, then demolition, rough-in, waterproofing, tile, vanity and fixture installation, and the clean. Typical durations per step are published once the operator confirms them. [TBC]

  1. Consultation and measure

    How many people use the room, tub or shower, storage, the fixtures you want to keep. We measure the room and photograph the plumbing and the panel.

  2. 3D design and quote

    Tile layout, vanity size, niche and bench positions, lighting and ventilation, every line priced. Change anything before sign-off; nothing is ordered until you do.

  3. Permit, if needed, and the vanity build

    Relocated fixtures, drainage changes or a new exhaust vent go to the City for a permit while the vanity is built in the workshop and tile, glass and fixtures are ordered.

  4. Demolition, rough-in and waterproofing

    The room comes out, plumbing and electrical are roughed in to the new positions, inspections happen, and the waterproofing system goes in and cures.

  5. Tile, vanity, fixtures, glass, clean

    Floors and walls tiled and grouted, vanity and top installed, toilet and fixtures set, glass measured and fitted, ventilation and lighting connected, final clean and walk-through.

Permits

Which bathroom work needs a Mississauga permit

Replacing the toilet, tub, shower or sink in the same location needs no building permit in Mississauga. Adding, removing or relocating any plumbing fixture, installing or altering drainage, or adding an exhaust fan vented outside is on the City of Mississauga's permit-required list; new circuits need an Electrical Safety Authority permit filed by the licensed electrician. We tell you which apply before you sign.

The City's own list of projects that require a permit (checked October 2026) names a plumbing fixture that is "added, removed or relocated" and "plumbing drainage — install, replace or repair" as permit work, and "plumbing fixture replacement in the same location" as no-permit work. A bathroom renovation that keeps the fixtures where they are is therefore usually permit-free; one that turns a tub alcove into a walk-in shower with a relocated drain is not. Electrical additions — a heated floor circuit, a new fan, more outlets — are inspected by the ESA before the walls close. Permit fees sit as their own line on the quote. Our permit guide covers the full list.

Pricing guide

What drives the cost of a bathroom in Mississauga

Bathroom renovation prices in Mississauga are driven by tile area and format, whether fixtures move, a custom tiled shower versus a tub, the vanity and countertop, glass, and electrical extras such as heated floors. Published Mississauga cost guides checked in October 2026 list full bathroom renovations starting around $15,000; Prime Kitchen and Bath quotes each room individually in CAD with HST separate, and publishes its own ranges once confirmed by the operator. [TBC]

Cost driverLower endHigher end
FixturesStay in the same positionsRelocated toilet, shower or tub; new drainage; City permit
Shower or tubStandard tub with tiled surroundCustom tiled walk-in or curbless shower, niche, bench, linear drain
TileStandard-format porcelain, simple layoutLarge-format, mosaic or natural stone; floor-to-ceiling; patterned layouts
Vanity and topSingle sink, laminate or entry quartz topDouble sink, tall storage, premium quartz or porcelain top
Glass and fittingsFramed door, standard fixturesFrameless glass, thermostatic valves, rain head and body sprays
Electrical extrasExisting circuits, new fanHeated floor, lit mirror, additional circuits, ESA inspection

Prices in CAD, HST extra. Every quote is written and itemised, and nothing is ordered before design sign-off. Ontario's Consumer Protection Act rules on written contracts, deposits and the 10-day cooling-off period are summarised on the warranty and terms page; the contractor-vetting guide applies to bathrooms just as much as kitchens.

Timing

How long a bathroom is out of action

Unlike a kitchen, a bathroom is out of use from demolition to the final fixture fit, because the waterproofing has to cure and the tile has to set before anything goes back in. Design, the vanity build and ordering happen beforehand while the room stays in use. Typical durations are published once the operator confirms them. [TBC]

If it is the only bathroom in the house, say so at the consultation: the sequence is planned to keep a toilet usable for as much of the job as the drainage work allows, and the days without one are named in advance. Demand for bathroom work in Mississauga follows the kitchen calendar — enquiries cluster after Labour Day for a pre-holiday finish — so a spring or summer design sign-off usually means a shorter wait for a start date.

Small rooms

Small bathrooms, powder rooms and condos

The 5-by-8 bathroom

The standard Mississauga family bathroom — tub along the short wall, toilet, vanity — is five feet by eight. The wins are a wall-hung or shallow vanity built to the exact width, a tub-to-shower conversion where the household never bathes, a large-format tile with few grout lines, a recessed niche instead of a corner caddy, and a mirror cabinet for the storage the vanity cannot hold. Keep the fixtures where they are and the permit stage disappears.

Powder rooms

Half the size and twice the visibility, because guests use them. A small vanity built to the wall, a bold tile or wall finish that would be too much in a big room, and good lighting go further here than anywhere else in the house.

Condos around Square One

The corporation approves the drawings first, the service elevator is booked, hours are restricted and the corridor is protected every working day. The plumbing stack is a common element, so fixtures almost always stay put and everything around them changes — which still produces a completely new room. The condo guide walks through the building process; it applies to bathrooms as written.

Accessible bathrooms

A curbless shower with a linear drain, blocking in the walls for grab bars now or later, a comfort-height toilet and a wider door are cheapest to build in during a renovation and expensive to add afterwards. Tell us if anyone in the house will need them within ten years.

Materials

Materials that survive a wet room

Tile

Porcelain for floors and wet walls — dense, low-absorption, available in large formats that cut grout lines. Natural stone wants sealing and a gentler cleaner; mosaics belong on the shower floor where the grout gives grip. Matte finishes hide water spots; glossy ones show them.

Vanity tops

Quartz is the default: non-porous, stain-resistant, consistent. Porcelain tops handle hot styling tools better. Granite works if sealed. Avoid laminate at the sink unless the budget demands it. The countertop comparison applies here too.

Fittings and glass

Thermostatic shower valves, solid-brass fixtures with replaceable cartridges, frameless 10 mm glass with a proper sweep, and an exhaust fan sized to the room and vented outside — the fittings decide how the bathroom feels at year five.

Questions

Bathroom renovation questions, answered

How much does a bathroom renovation cost in Mississauga?

Published Mississauga cost guides checked in October 2026 list full bathroom renovations starting around $15,000, rising with tile area, a custom shower, moved fixtures and premium fittings. Prime Kitchen and Bath quotes every bathroom individually after an in-home measure, in CAD with HST shown separately; our own ranges are published here once confirmed by the operator. [TBC]

How long does a full bathroom renovation take?

The room is out of action from demolition to the final fixture fit; waterproofing cure times and tile setting are the steps that cannot be rushed. Typical durations are published once the operator confirms them. [TBC]

Do I need a permit to renovate a bathroom in Mississauga?

Replacing the toilet, tub, shower or sink in the same location needs no building permit. Adding, removing or relocating any of them, altering the drainage, or adding an exhaust fan vented outside is on the City of Mississauga permit-required list. New circuits need an ESA electrical permit filed by the electrician.

Can you move the toilet or the shower?

Usually, in a house — it becomes a plumbing fixture relocation with a City permit and drainage work priced as its own line. In a condo the stack is a common element, so the corporation must approve any drainage change first, and many do not.

Do you build the vanity?

Yes. The vanity is a cabinet, and cabinets are what the Mississauga workshop makes: built to the wall width and the plumbing position rather than a catalogue size, with the same drawer hardware as our kitchens, and a quartz, granite or porcelain top templated after it is installed.

Tub or walk-in shower?

Keep at least one tub in the house if you plan to sell to families; convert a second bathroom to a walk-in shower if the household never bathes. Curbless showers need the floor built for the slope and the waterproofing detailed for it — decide before the design, not during the tile.

Can you renovate a condo bathroom?

Yes. Condo bathrooms need the board's approval of the drawings, elevator bookings and restricted hours, and the plumbing stack is a common element — fixtures usually stay where they are and everything around them changes.
